ci: fix theme docs generate bug

* Added "Shadow" set (Red, Green, Blue, transparent BG)

3 additional themes sticking primarily to flat colors, which the exception of icons and border being slightly darker. All 3 themes also have transparent backgrounds that will show differently per-user via GiHub's own light and dark themes. Transparency should also still provide easy readability for both.

* Test

Just want to see if we can make the themes have a transparent background.

* Shadows moved under Transparent
